Chapter 27: Nurse Duckett
In Chapter 27 of Catch-22, Yossarian and Dunbar try to plead insanity to avoid flying more missions, but their plan backfires when they are mistaken for other soldiers and A. Fortiori is sent home instead. Yossarian becomes angry and goes to see Doc Daneeka, but Daneeka refuses to ground him for insanity, asking who would be left to fight if all the insane men were sent home. Yossarian and Dunbar also encounter Nurse Duckett in the hospital and try to touch her inappropriately, but are stopped by an angry doctor. Yossarian tells the hospital psychiatrist, Major Sanderson, that he has a recurring dream about a fish and believes that people are trying to kill him. Sanderson thinks that Yossarian is truly crazy and should be sent home, but the mistake with Yossarian and Dunbar's identities prevents this from happening.
